Chapter 4 - Using Your Modem

Operating Your MultiModemZPX

If you’re an experienced modem user, you may only want to check your modem’s settings for data compression, error correction, and so on.You’ll find you can get moving quite quickly by using a terminal window (you may use HyperTerminal in Windows) to issue the AT&V<cr> command. This command will list your modem’s current configuration, the stored (user) profiles, and the stored telephone numbers. If you come across a setting you’re unsure of, refer to the AT Command Reference Guide for AT commands and S- Register explanations and defaults.

Your MT5634ZPX can be controlled by issuing AT commands and setting S-Registers. Since your MultiModemZPX default settings use a traditional modem set to make a dialup call to a remote installation where the call is answered automatically—you shouldn’t need to change the current configuration.

In operating your MultiModemZPX, it is likely that you will use your data communications software to either:

•Enter terminal mode, where you can speak most directly to the modem by issuing AT commands, or

•Launch a data communications or Dial-Up Networking session through a set of modem configurations that you select and then associate with a target telephone number.
